So if you are going to meetings in a city where a friend lives and you don't want to pay for a hotel because you are a student, is it appropriate/polite to ask if you can stay with her for a night or two? If so, how should you do this?
We are old friends from high school that had some overnights back in the day with a mutual friend, but have since largely fallen out of touch except for a get-together once or twice a year...
